Hydrophone Calibration
Do you need high-accuracy hydrophone calibrations that are traceable to NIST standards, or hydrophone calibrations as a function of temperature and pressure? GeoSpectrum can measure the pressure sensitivity of a hydrophone with 0.2 dB absolute accuracy.

Hydrophone Life Testing
The sensitivity and capacitance of a hydrophone should be stable during its expected life. In a matter of weeks, GeoSpectrum’s suite of tests simulates years of life.
